Fedora Networking :: Samba Transfer Speed
Jan 10, 2010
So what kind of speed are you getting with Samba over your local network? What speeds should I be seeing? I'm currently transferring a large amount of files from one computer to another. I'm taking everything off of a desktop drive on computer A and putting it on an IDE disk on computer B. Transfers are running at around 600-700 KB/Sec. I've seen moments, mostly when the transfer starts, where speeds were at 1000KB/Sec, but that lasts a very short while and then starts to "degrade" until it reaches 600+ KB/Sec. It then seems to level off there. Is this acceptable? Is this all I can expect to get out of a 10/100 home network? The current transfer is 2.5GB. Looks like it will take 1 hour+ to complete. Transferred 12GB last night. Was looking at 4-5 hours to complete so I left it running while I was sleeping. Personally, I think this is slow. I think it could be exponentially faster.
While I'm running these transfers I'm looking at some documentation on Samba speed tweaks. I've been adding little tidbits here and there to both smb.conf files. Some of it seems to help. Sometimes there is a noticeable difference in speed. Sometimes the changes actually cause degradation in speed. If you have a speed tweak that you would like to share the information will be gratefully accepted. Samba gurus welcome to reply. How do you set up Samba in an office environment? How do you set Samba up in an environment where performance is critical?
Maybe I should forget about Samba and try using a different transfer protocol? Am I expecting too much from Samba?I should stop before I really start to ramble. Anyhow, networking beats the heck out of the sneakernet, at any speed!As a side note, or maybe quite importantly, there is a router and a network switch (not a hub) involved here. Maybe something to consider?

(this is a repost of the same thread in the networking/wireless forum, I think it's better suited here but couldn't see a way to move it) I have a Proliant Microserver, I have Ubuntu Server 10.10 installed onto to a USB stick (the server has an internal USB port). The storage drives are Samsung SpinPoint F1s. The server is plugged into a gbE switch, there is a link from that to a 200mbps powerline link, from there it goes to a 100mbps switch and then to my machine I was testing from.
I realise that a powerline link can often slow things up, but I use the same link for my Internet connection which will happily pull files down at around 4.3mb/s.. so I know the link isn't the bottleneck. If i copy anything via any of the samba shares then it transfers at around 1.5mb/s. This speed does not change if I try plugging the client into the same gbE switch as the server. Similar spees are shown if i transfer it over http via apache2 as well. Client machines are laptop running ubuntu and a win7 desktop. Speeds are the same copying to both of them. I have applied tweaks to samba as described here;

I have the problems with transfer speed between samba and Windows XP clients.
Samba server configuration:
Quad Core 6600 CPU.
4 Gb RAM
OpenSUSE 11.2 with kernel "2.6.31.12-0.1-desktop"
Samba - samba-3.5.1-1.1.i586
Test: 4 GB File copying. One file.
Transfer speed from Samba Server to Windows 7 and XP clients:
(Windows clients copy file from Server share -> to local drive)
From Server to Windows 7 client 1:
85-90 Mb/sec
From Server to Windows 7 client 2:
90-100 Mb/sec
From Server to XP1 client 3
75-100 Mb/sec
Transfer speed from Windows 7 and XP clients TO Samba Server:
(client copy file from local drive -> to server Share)
From Server to Windows 7 client 1:
12-20 Mb/sec
From Server to Windows 7 client 2:
30-35 Mb/sec
From Server to Windows XP client 1
20-27 Mb/sec
(Copying file from Windows local drive to Windows remote share)
From Window 7 client 1 TO Windows XP client 1
40-50 Mb/sec
From Window 7 client 2 TO Windows XP client 1
50-60 Mb/sec
Copying file from Windows 7 client 2 share -> TO Windows XP client 1 show me 100-120 Mb/sec speed permanent.
Copying file from Linux hosts to NFS server is stable 50-90
Mb/sec bidirectional.
This part of my smb.conf file
Code:
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.
# Date: 2009-10-27
[global]
log level = 1
debug level = 0
max log size = 50 .....
I have very slow write speed when copying file from Windows clients to Samba Share. Samba speed is slower than Windows native clients connections ?

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab
When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s
But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.

I had a F14 samba server working flawlessly now for a quite time. Unexpectedly about a month ago the write speed slowed down around 64kbit/s and that's really slow. I haven't changed any configs, only updated the server. I've troubleshooted this from many angles:
-It is not a network issue because sftp writes are good.
-It is not a RAID1 issue because write speed from another directory (locally) are good.
So basically samba is the only thing left.
Here's example from smb.conf:
[MyShare]
comment = My share
path = /mnt/RAID_share
writeable = yes
browseable = yes
writelist = +smbuser
Here's a snip from logs today:
[2011/08/04 09:04:27.509273, 1] smbd/server.c:267(remove_child_pid)
Scheduled cleanup of brl and lock database after unclean shutdown
[2011/08/04 09:04:47.526336, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown
[2011/08/04 09:17:57.634660, 1] smbd/server.c:267(remove_child_pid)
Scheduled cleanup of brl and lock database after unclean shutdown
[2011/08/04 09:18:17.635196, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown .....
There's a restart that is not software related.

I just noticed that files are transferring between my two computers at no more than 11.3Mb/s no matter what I do.
I regularly use sshfs to mount a drive on my main computer. But after noticing a dismal speed of 10Mb/s when copying a file, I thought maybe sshfs is slow. So I tried scp, and I'm getting 11.3Mb/s with scp. Using the blowfish cypher gave me no change to this, still exactly 11.3Mb/s.
I have a Gigabit network except for the cable, which is a 10meter, 100Mb/s cable.
I have a custom modified sysctl.conf file which I'll post here if needed.
Is there anything I can do about this pathetic speed ? Maybe a modification to my ssh config ? sysctl ? anything ?

We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.

I recently setup my two PC's for network file sharing using Samba. I notice the max speed I can transfer a file is 89kb/s instead of 100Mb/s. How can I increase the speed to max 100Mb/s? Both systems are running Ubuntu 9.10 w/Samba.

I'm experiencing slow speed transfer between two wireless connected laptops running ubuntu 9.10. Using SSH to tranfer files between these two laptops, which connect to the internet via a wirelesss router, with good speed. This is why I'm surprised by this low speed : 52.3 KB/s, averaging 3 hours and 31 minutes for a 700 Mb movie. Is there any way to make this faster ?

I was wondering how to calculate some problems related to network transfer speed. If someone can show me a function to calculate network transfer speed over time, I would appreciate it.I'm in the midst of transferring 1.3TB of data to a network storage system. By looking at the stats, 4.6GB file transferred out in 6 min and 30 seconds. How long would it take to transfer 1.3TB of data?

I am running Fedora-13 64 bit on my Dell Laptop, The same Laptop has Windows-7 as well (dual boot system). I have chosen ext3 filesystem while installing fedora. The file transfer speed in Fedora-13 over the network to my network drive comes out to be not more than 5MBPS.Where as in Wndows-7 I am getting the speed of around 10~12 MBPS. Also I found that copying files in USB flash drive is very slow than in Windows-7 . What could be the problem? To add it , I have another Laptop Running Ubuntu-10.04 , which also performs network transfers at 10~12 MBPS. So its just the fedora-13 who has this problem. As far as I remember this was not the case with Fedora-12

I have Samba share setup on my Laptop running Lucid Lynx, for my home network,wireless The copy speed for my movies, when I access them from Windows laptop is too pathetic. Took 22 min to copy around ~1.6GB of data, giving me a speed of only 1.2 MB/s
Haven't seen nething that bad What settings do I have on my server which can improve the copy speed ??Smb.conf is pretty simple and default
Code:
[global]
workgroup = WORKGROUP
netbios name = scooby-laptop
server string = "ScoobyDo server (Samba, Ubuntu)"
dns proxy = no
log file = /var/log/samba/log.%m

When i try to copy files from my samba server (Ubuntu 9.10) to my windows seven media center, the speed is extremely slow. So slow that is better to download 100mb file from the internet, than from my lan. And on my lan, every card and switch is at 1000 mbps speeds on cat5 cables. And from XP or other linux machine

I have a 500gB USB drive connected to my laptop for backups and filestorage. But I can't get it to play nice with Midnight Commander. My transfer speeds max ut at 2MB/s wich is painfully slow when moving large files such as movies. Worker FM transfers the same files to the same drive much MUCH faster (not sure by how much, though). This leads me to the conclusion that the problem lies with MC.

I have two machines running open vpn connected trough a 8 port Gigabit switch (Tp-link TL-SG1008D). The problem is when I try to transfer a file the transfer starts at 13 mb/s and drops to 300kb/s. When I replaced the ram on the two machines and restarted the transfer the speed was 13mb/s constant. How does changing the ram makes such differences (at the first transfer they had 512mb at the second transfer the machines had only 128mb) ? Os Ubuntu Server 10.04.2 LTS
PS :Tried with 256 ram and the problem persists...
Machines: two hp d530

slow usb transfer speeds has been resolved in 11.04 (Natty Narwhal)? I am currently using Lucid and facing the problem of slow usb transfer speeds which has always been there in ubuntu but everything else is running just fine for me so I see no reason to upgrade yet unless the new OS has solved this problem.

I'm trying to transfer some files to my USB stick, and it's transferring at the most pitiful rate, around 200-400kb/s, occasionally shooting up to 1MB/s, but not for more than a few seconds.
I realize a lot of factors can play into this, so I'll try to provide as much detail as I can.
I'm using OpenSUSE 11.3, KDE 4.6 RC2, and a Corsair Mini Voyager 16GB. My motherboard is a Gigabyte EP45-DS3L.
dmesg output:
Code:
lsusb -t output:
Code:
Sometimes too, the transfer just stops all together. It just... doesn't transfer for a while, then it'll go back to 400kb/s etc, then it'll stop again for a minute.

what might cause a file transfer to start out fast (11-12 mb/sec) and then drop to about 1 mb/sec after having downloaded about 2 gb? This is what happens when I download files from my old fit-pc 1.0 (a small mini PC with 256 MB/RAM, an AMD Geode processor, and a 100 mbps network card) via ftp over my local network. Is it some buffer filling up?
I was directed to some article about "bufferbloat" earlier [URL], but I did not get any solution from that unfortunately. I have tried increasing the server's TCP buffer using these instructions: [URL] , but it does not make any difference. By the way, I am running Ubuntu Server 10.10 on the fit-pc and Ubuntu 10.10 desktop on the connecting client (which is just a normal Core 2 duo, 4 gb ram computer).
UPDATE: I should add that things were working fine when I was using ubuntu 7.10, but are not now that I have installed 10.10...
UPDATE 2: I just found out this is ONLY a propblem when transferring files to ubuntu. If I use winscp from Windows 7, the transfer speeds are fine...
UPDATE 3: It seemed it was gFTP that was the culprit. Transferring the files using filezilla instead in Ubuntu yields an excellent rate of 11.8 MB/sec. Anyone have an idea what might be wrong with gFTP?

I connected a 16GB SDHD Class 4 card to my PC with a dongle reader. A class 4 card is supposed to support a minimum of 4 MB/s sustained speed. I grabbed a couple of large, 4.4 GB each, files and copied them to the SD card with Nautilus. The transfer rate started out at 60 MB/s and rapidly dropped to 50 then 40 and slowly dropped to 3.5 MB/s after about 3 GB transferred and it is still dropping.The PC will copy from drive to drive at 65 MB/s so I do not think the issue is reading from the hard drive.I am confused about the transfer speeds which Nautilus is showing. Obviously I am not really transferring to this card at 50+ MB/s. If I was moving data from hard drive to cache I would expect much more speed - I have 8 GB of RAM on the PC. That said, I have stopped the transfer and attempted to unmount the card. I get the message "Failed to eject media; one or more volumes on the media are busy." This has been going on for several minutes so some activity is going on in the background.

About NFS.
Server:
Client(s):
Code:
I have followed Robbie Workmans' HowTo [url]
Reading and writing works absolutely fine with small files but large files are tediously slow in writing to the server. (rw,no_subtree_check) are options in exported directories.
What is your experience with NFS and how can I speed up large file/folder transfer(write) speeds?

My Sempron LE-1100 home server (1GB RAM) has run CentOS 5 32-bit happily for years, but I decided to replace its two Seagate 250GB drives (RAID1) with two WD 500GB black drives (RAID1). I decided to do a fresh install and used CentOS 5.5 64-bit this time. Since switching to the 64-bit OS with the new drives, my transfer speed across the LAN has dropped from a reliable 45MB/s to only 18MB/s from other machines to the server, and to 27MB/s from the server to other machines on the LAN. I use gFTP or WinSCP for these transfers (in FTP mode). Prior to installing the new WD drives, I ran the long WD tests on them and they passed, so I don't believe the drives are faulty. I suspect it's more to do with me switching CentOS from i386 to x86_64.
I've got two questions:
1. Is the 64-bit version of CentOS appropriate for a Sempron LE-1100 with 1GB ram, or should I switch back to the i386 version?
2. Is there a reason why switching to the 64-bit OS would negatively impact on transfer speeds? I doubt the new HDDs are faulty...I was expecting them to be faster.
3. Is there anything I can try to improve transfer speeds across the LAN?
According to PHPSysInfo, the network card is "Ethernet controller: nVidia Corporation MCP67 Ethernet".

I want to use samba for file sharing like on a Windows home network. Actually they are all Linux machines but nfs is too complicated. On my host machine I installed samba and system-config-samba. I created a new share for /home, check marked writable and visible and put access to everybody. For preferences-->server settings--> security the "authentication mode" is set to user, encrypt passwords is no, and guest account is no guest account. Under preferences-->samba users I added myself as a user with the same windows user name as my Linux user name and the same password.
My client is a virtualbox fedora (used for testing purposes but actual clients will be real computers on my home network). I entered the address smb://192.168.1.184. When asked for the user name and password I put my regular user name and password since that was what I set in samba users. However, the password dialog keeps coming up and won't let met into my own computer. If I quit it says something like access is denied. How can I get my home network back? I liked this feature when my home computers ran XP but I switched them to Fedora 12.

I am experiencing the slow transfer speed from my Lenny to Windows 7. Both of my NIC's are oboard Nvidia nForce 1GBPs. For example 200MB transfer from Win to Lenny (default samba shares) takes about a minute, while the other way around takes an hour!!!. I get similar transfer behavior through sFTP.
Can somebody clarify if the problem is in NIC drivers, MTU (I can't set it up higher than 1500), or smb.conf settings

I've done this a million times, so sure it is something simple. I just set up a file server with three drives. One is small and faster that houses all the system files. Then the other two are slower but larger (WD Green: variable 5,400-7,200 RPM) drives in RAID0 then encrypted using Blowfish 256-bit. Hence the performance double then hit below in the buffered reads.
Code:
Debian-Server-023 ~ # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1650 MB in 2.00 seconds = 825.44 MB/sec
Timing buffered disk reads: 234 MB in 3.02 seconds = 77.41 MB/sec
Debian-Server-023 ~ # hdparm -tT /dev/md0

I am newbie to linux, I am dealing with Fedora core 13. I have already succeedded in building an ad hoc network and a WLAN network. My next step is to get some networking statistics such delay, throughput, etc. So, I need traffic to flow through the network for both multimedia traffic and bulk data traffic. How to send files between nodes on the network (I found commands ftp, rcp but do not know whether they are the correct choice for this). ID their any application to perform this?
Also, I want to perform some video streaming between two nodes to study the behavior of real time data transfer. Is thier any application to perform this?
